What is birth control, and how does it work?

Birth control works to prevent pregnancy in different ways.
  • Hormonal birth control methods work by preventing ovulation so that a woman is temporarily infertile.
  • Barrier methods of birth control prevent the man's sperm from reaching an egg.
  • Barrier methods include
  • diaphragms,
  • condoms, and
  • cervical caps.
